What is Sequence Generator Transformation?

Grouping generator change is inactive so it doesn't influence the number of info lines. The grouping generator is utilized to create essential key qualities and it's utilized to produce numeric succession values like 1, 2, 3, 4, 5, and so forth.


For instance, you need to dole out arrangement values to the source records, then, at that point, you can utilize the succession generator. The created succession values can be like 5, 10, 15, 20, 25, and so forth, or 10, 20, 30, 40, 50, and so on. contingent on the designed properties of the change.

To produce the succession numbers, we generally utilize the NEXTVAL segment.

Properties of Sequence Generator Transformation


Begin Value - It is the primary worth that will be produced by the change, the default esteem is 0.

Increase by - This is the number by which you need to augment the qualities. The default esteem is 1.

End esteem - It is the most extreme worth that the change ought to create.

Cycle - on the off chance that this choice is set, subsequent to arriving at the finish of the worth, the change restarts from the very outset esteem.

In this model, we will produce succession numbers and store in the objective.


Stage 1 - Create an objective table with the accompanying content.


Stage 2-Import the table in Informatica as target table


Stage 3 - Create another planning and import EMP source and EMP_SEQUENCE target table

Stage 4 - Create another change in the planning


Select grouping change as the kind

Enter change name "seq_emp"

Select Create choice

Stage 5 - Sequence generator change will be made, select the done choice

Stage 6 - Link the NEXTVAL segment of grouping generator to SNO section in target

Stage 7 - interface different sections from source qualifier change to the objective table

Stage 8 - Double snap on the grouping generator to open property window, and afterward


Select the properties tab

Enter the properties with Start esteem =1, and leave the rest properties as default

Select OK button

Grouping Transformation in Informatica with EXAMPLE


Presently save the planning and execute it in the wake of making the meeting and work process.


The snow section in the objective would contain the succession numbers produced by the arrangement generator change.


In our model, the groupings will be like 1 - Scott, 2 - King, 3 - Adam, 4 - Miller, and so forth.
